The spectral linewidth of a flashlamp-pumped dye laser

Abstract
The rate equations for the molecular state densities and mode photon densities are set up for a flashlamp-pumped tunable dye laser. These are solved numerically for a typical rhodamine 6G laser tuned by a Fabry-Perot etalon and the results compared with experiment. The untuned dye laser line shape is also calculated and compared with experiment.
